Who likes watching the stars at night? Well, to be able to see the series of stars more clearly then you need star binoculars. Telescope or telescope is an optical instrument used to capture objects that are very far away.
Initially, these binoculars were functionally used to catch and see stars in the sky or other distant things. Over time, these binoculars became an observation instrument that technically accumulated electromagnetic radiation.
Not only that, these binoculars at the same time form an image rather than the shape that is seen. According to Arwin Juli in an article entitled Medieval Islamic Astronomical Treasures, this star telescope or telescope is a key instrument in astronomical observations.
Star Binoculars Function
Binoculars as a tool to increase the size of the angle of objects and their brightness has three main functions. Here are its three main functions:
- To collect as much light as possible from an object
- To focus light to create a sharp image
- To increase the size of the image
This magnification is a general function of binoculars. Mainly, as a comparison between two different general astronomical objects, such as one object being clearly visible and the other object having to use binoculars to zoom in.
The most important property of binoculars lies in their ability to accumulate telescope light. The larger the gap in the telescope tube, the more light will be collected.
According to the Journal of Islamic Astronomy and Related Sciences, there are six important sections in telescope which supports the main function of the telescope. Here are the six important parts of the telescope:
- Telescope tube is a place on the main lens located on binoculars or telescopes
- Finderscope is the inside of the binoculars attached to the main tube
- The eyepiece is a function of the ocular lens in the binocular system
- The focuser is the inner part of the binoculars which is divided into various styles
- Mounting is the main drive system on star binoculars which is equipped with a latitude control knob, latitude altitude scale, and others.
- Tripod is a leg to support binoculars stars above the surface
Types of Star Binoculars
Did you know that there are three types of binoculars, which generally have their own specifications and functions. The explanation of the three can be seen in the following review:
1. Refractory Star Binoculars
This type of refractor telescope is part of a refracting telescope that has a lens as an instrument for capturing light and implementing its function as a telescope.
Galileo Galilei was the person who first invented the telescope by making a small type of refractor in 1609. There are two convex lenses in the telescope of refractor stars, namely the objective lens and the eyepiece lens.
2. Reflector Star Binoculars
Furthermore, there are reflector star binoculars that use a mirror as a substitute for a lens that captures light and reflects it. This type is very suitable if implemented to observe several objects such as galaxies, nebulae, and comets.
3. Catadioptric Binoculars
Finally, there are catadioptric binoculars, which are a symmetrical combination of refractor and reflector types. Where these catadioptric binoculars use two mediums to accumulate light, namely mirrors and lenses.
